How to trigger jobs manually in Packit
Packit is an open source project aiming to ease your project's integration with Fedora Linux, CentOS Stream, and other distributions. Packit is mostly used by projects that build RPM packages. We won't go through the onboarding process that was already described in a previous article, but we would like to introduce you to new features that were recently promoted into production.
Testing Farm execution
From Packit, you can easily trigger the tests on Testing Farm even without building the RPMs. This is very handy for projects that basically don't build RPMs but want to use these two services for verifying the code. As a good example, we can refer to the Strimzi project where users consume container images.
In such cases, the users want to trigger the tests, verify the code and see some output. This option is available from the beginning. Users can easily define when to execute the tests for every pull request, commit, or release. That sounds pretty cool; however, when you have complex tests (5+ hours per test run) as we have in Strimzi, you probably don't want to trigger all tests for each commit. So, how can the users achieve that?

Using if-else in Dockerfile
Docker is an essential tool for containerizing applications, making them portable and isolated. The Dockerfile is a key component in the Docker ecosystem, allowing developers to specify how their application should be containerized. Often, there is a need for conditional logic in Dockerfiles, much like you would find in programming scripts.

60 Seconds of WIP, 7 September 2023
Run Your Own Mail Server has finally forced me to write a bit about netcat versus telnet. Netcat is a flexible network tool that, among other things, allows you to connect to arbitrary TCP/IP ports. We’ll use it for testing services.
